SR170 & serial printer cannot print !!!

We are trying to configure & printing to Olivetti PR2E serial printer from SunRay 170 via serial cable (COM B). We have set the Printer Make as IBM and Printer Model as IBM ProPrinterII.

Unfortunately, when we tested print /etc/hosts file, it printed a junk "**********" characters. We did change the setting of Printer Make as Olivetti and Printer Model as Olivetti PG306 but it printed junk again.

We also tried connect the printer to COM A but this time the printer does not print anything.
